CHAPTER 2:
SIGNALS, SIGNS AND PAVEMENT MARKINGS
This chapter provides the information you need to know about Pennsylvania roadways. It covers:
• Signals
• Signs
• Pavement Markings

SIGNALS
Traffic signals are installed at intersections to control the movement of vehicles and
pedestrians. Traffic signals are arranged in either vertical lines or horizontal lines.
When they are arranged vertically, red is always on top and green on the bottom.
When they are arranged horizontally, red is always on the left and green on the right.

RED, YELLOW AND GREEN TRAFFIC LIGHTS AND ARROWS
When there is a STEADY RED LIGHT, you must stop before crossing the marked stop line or
crosswalk. If you do not see any lines, stop before entering the intersection. Wait for a green light

You may turn right while the light is red, unless a NO TURN ON RED sign is posted at the intersection.
You must first stop, check for and yield to pedestrians and other traffic.
You may also turn left after you stop at a red light, if you are in the left lane and are turning left from a
one-way street onto another one-way street, unless a sign tells you not to turn. You must first stop and
yield to pedestrians and other traffic.
A STEADY YELLOW LIGHT tells you a steady red light will soon appear. If you are driving toward an
intersection and a yellow light appears, slow down and prepare to stop. If you are within the
intersection or cannot stop safely before entering the intersection, continue through carefully.
A STEADY GREEN LIGHT means you may drive through the intersection, if the road is clear. You may
also turn right or left unless a sign tells you not to; however, when turning, you must yield to other
vehicles and pedestrians within the intersection.

 

A GREEN ARROW means you may turn the way the arrow points. When you turn during the green
arrow phase, your turn is “protected”...
